The two may be formed integrally with the locomotive 50 sections of the hub liner are adapted to be seor car wheel, as may also the base ring 59. If cured in assembled relationship by means of desired, the hub liner may be located at the inkeepers 28 and 29, provided with prongs 30 and nor side of the wheel in those cases where the 3|, respectively. .The liner sections are-"each journal box is located inwardly from the wheel.

Hence, there is no opportunity for either the liner or the wear plate tocontact with and wear grooves in the axle.

In normal operation of the device, the wear occasioned by thrust of a wheel in the direction of the journal box will be taken principally by the full floating sectional hub liner, this being preferably made by material, such as bronze, or similar material adapted to effectively cooperate with carbonized steel wear plates 2| and 4|. The bearing faces between the wear plates and the hub liner may be lubricated.

The space between the wear plate 4| and the hub liner receives lubricant through pipes or passages in the journal box. The opposite face of the hub liner may receive lubricant injected through fittings .4 secured to the wear plate 2|. The edge of the hub liner is lubricated through fittings attached to opening 46, as shown in Figs. 2 and 5. Or, grease cups could be substituted for such fittings, if desired. When the bearing faces of the hub liner have worn down to such an extent that renewal is necessary, the nuts 45,

secured to the ends of bolts 38, may be removed from one of the half sections of the retainer ring. The other half section can. be left in place. And the full floating hub liner can be turned to such position that the keeper comes into position for inspection by workmen. Thus, if the thickness of the hub liner substantially coincides with the thickness of the keeper, this fact will indicate that the amount of wear to be tolerated has been reached. Then, first one keeper can be removed with an outward motion, then the hub liner turned to permit the other keeper to be removed. This will free one section of the worn hub liner.

Similarly, the other section may be turned to permit removal. Thereupon, new sections can be inserted and held in assembled relationship by either the 01d keepers or new keepers. Upon such renewal, the removed section of the retainer ring can be replaced. This whole operation can hence be readily accomplished without removing the wheels or axles from the locomotive or without any extensive dismantling of the locomotive. This effects important economies in railway maintenance, due to the speed with which the change is made.

While we have described quite specifically the particular embodiment of the invention herein illustrated it is to be understood that various changes and modifications may be made by those skilled in the art without departure from the invention as defined in the appended claims.

What we claim is:

1. In a device of the character described in combination with av wheel and journal box, a full floating hub liner comprising a plurality of sections detachably secured to one another, a wear plate secured to the wheel and engaging one face of the hub liner, a second wear plate engaging the opposite face of the hub liner and secured to the journal box, and means carried by the wheel supporting the hub liner with freedom for rotation relatively to the wheel, said means confining the exterior of the liner and being effective to prevent it from falling to the track in the event that the said sections become accidentally disconnected.

2. In a device of the character described, the combination of a journal box, a wheel, a full floating hub liner comprising separate sections having tongue and groove connections at their contacting edges, removable keepers bridging said tongue and groove connections and normally preventing separation of said sections, a sectional retainer ring having a counter-bored portion in which the hub liner is mounted with a working fit and having a shoulder portion overlapping one face of the liner, the wheel carrying means to which the retaining ring is detachably secured.

3. In a device of the character described, the combination of a wheel, a journal box, a hub liner comprising separate sections detachably secured to one another, a base ring secured to the wheel, at a point spaced radially from the hub, and a retainer ring secured to the base ring and having an annular groove forming a bearing portion in which the hub liner is mounted with freedom for rotation relatively to the wheel, said I retainer ring enclosing the exterior of the hub liner and being effective to prevent it from falling to the track in the event that said sections become accidentally disconnected.

4. In a device of the character described, the combination with a wheel and journal box, of a hub liner between them comprising separate sec-' tions each having recessed portions formed in the peripheral edges thereof with keepers therein detachably uniting the sections and an annular bearing ring formed in separately removable sections on the wheel for supporting said liner, with freedom for rotation relatively thereto, said keepers being of less thickness than said liner and adapted to serve as a thickness gauge, and one of said bearing ring sections being adapted to be temporarily removed to expose said keepers to view.

5. In a device of the character described, the combination, with a wheel and journal box, of a floating hub liner between them comprising separable sections normally held in assembled relation by a removable keeper whose thickness is less than that of said sections, and a shouldered retaining ring secured to the wheel and supporting the liner on the wheel with freedom for rotation relatively to the wheel, said retaining ring enclosing the exterior of the hub liner and being effective to prevent it from falling to the track in the event that said sections become accidentally disconnected.

6. In a device of the character described, the combination with a wheel and journal box, of a floating hub liner between them comprising separable sections normally held in assembled relation by a removable keeper seated in a recess in the face of the liner, a sectional retaining ring detachably secured to the wheel and having a counter-bored portion making a. Working fit;with the periphery of the hub liner and having an annular shoulder overlapping the outer face of the liner, said retaining ring enclosing the exterior of the hub liner and being effective to prevent it from falling to the track in the event that said sections become accidentally disconnected.

7. In a. device of the character described, the combination with a spaced wheel and journal box of a hub liner between them comprising separable sections normally held in assembled relation by a removable keeper having prongs which engage sockets formed in the peripheral edges of said sections and a sectional retaining ring secured to the spokes of the wheel and having a counterbored portion making a working fit with the periphery of the hub liner and having an annular shoulder overlapping the outer face of the liner, said retaining ring enclosing the exterior of the hub liner and being effective to prevent it from falling to the track in the event that said sections become accidentally disconnected.

8. A hub liner of the character described adapted to be interposed between rotary and nonrotary elements comprising separate sections jointly forming a ring-like plate, the peripheral edge of each section being recessed adjacent its end and keepers seated in the recesses for de- 10 tachably securing the sections to one another,

adapted to be interposed between rotary and non-rotary elements comprising a pair of separate sections jointly forming a ring-like plate, the peripheral edge of each section adjacent. its end being recessed, and having a socket in the bottom of said recessed portion, and keepers wholly accommodated in said recessed portions having prongs for engagement with said sockets so as to detachably secure the sections to one another, said keepers being of a predetermined thickness less than that of said liner and adapted to serve as a gauge to indicate when the liner has become worn to an extent requiring renewal.
